Sven Co-op is a Co-operative based game for Valve Software's Half-Life. In this mod, players must work together against computer controlled enemies and solve puzzles as a team. It is essential that you are at least familiar with Half-Life and its controls, and it is recommended that you have completed Half-Life's Hazard Course. While Sven Co-op is similar to Half-Life, with similar weapons, monsters and characters, the difficulty has been increased.

Sven Co-op's levels are set as missions and are generally separate from each other. Many missions span several maps, and some are collected together in a series. The aim of most levels is to reach the end or to achieve an objective / obtaining a high score is not essential to beat a level, its just part of the fun.
